Tripping or doing something dumb

acting stupid or any annoying behavior

Frantic and compuslive behaviour often associated with methamphetamine abuse (crank). People who regularly abuse crank may find themselves unable to stop a particular random activity like searching drawers, having sex, or putting things apart. This is called tweaking.

Repeatedly and obsessively engaging in a SIMPLE behavior or motion, like pulling at one's face to remove imagined objects that aren't there. Persons addicted to methamphetamine will engage in this type of compulsion. Yet, it is a myth some people subscribe to , that the behavior can extend to having sex. People high on meth can't perform anything NEARLY that complicated when they're tweaking, let alone maintain an erection or climax.

To describe someone that is out of thier mind or making a mistake.
